What does the percent yield of a reaction measure?
It measures the amount of reactants actually produced in a reaction compared to the amount that would theoretically be produced if 100% of the reactants were converted to products according to the stoichiometry of the reaction. It is found by: actual moles of products ÷ predicted moles of products * 100%
What is a coefficient in a equation?
The coefficients in a chemical equation represent the amount of moles of each substance involved in the reaction. On a smaller level, it also represents the amount of particles that have to collide or are produced in the reaction. Consider the following example: CH4(g) + 2O2(g) (arrow) 2H2O(l) + CO2(g) The coefficent behind oxygen in the reactants means that 2 molecules of oxygen have to collide with 1 molecules of methane to react. The coefficients in the products mean that this reaction produces 2 molecules of water and 1 molecule of carbon dioxide.
What acts as an acid in the following reaction NH 3 plus PH 3 - NH 2- plus PH 4 plus?
As you have it written NH3 donates a proton to the solution and this hydrogen ion is picked up by PH3 to make PH4; so NH3 is the acid here. ( though this reaction seems odd to me )
According to the following reaction how many grams of sulfur are formed when 37.4 g of water are formed?
To determine the grams of sulfur formed, we need to first identify the balanced chemical equation for the reaction involving sulfur. Once we have the balanced equation, we can use stoichiometry to determine the mass of sulfur formed using the given value of water formed.
What of the following is necessary to determine the rateof the reaction using the rate law?
To determine the rate of the reaction using the rate law, you need the rate equation that relates the rate to the concentrations of reactants. It is also essential to have experimental data, such as the initial rates of reaction at different concentrations of reactants, to determine the rate constant and the order of the reaction with respect to each reactant.
What is a reaction that produces gas called?
A reaction that produces gas is called a gas-evolving reaction or a gas-forming reaction.
How do you determine the limiting agent and excess?
The limiting agent in a chemical reaction is the reactant that is completely consumed first, stopping the reaction. To determine the limiting agent, calculate the amount of product each reactant can produce and identify the one that produces the least amount of product. The other reactant is then in excess.
What defines exothermic reaction?
A reaction that produces heat
How would you know if a reaction was endothermic or exothermic?
You can determine if a reaction is endothermic or exothermic by observing whether heat is absorbed or released during the reaction. If heat is absorbed, the reaction is endothermic. If heat is released, the reaction is exothermic. You can also measure the temperature change of the surroundings to confirm the type of reaction.
What do you call a mixture that produces a chemical reaction?
A mixture that produces a chemical reaction, scientifically speaking, is a chemical change.
To determine which of the products and precipitation reaction is the precipitate which of the following should you follow?
To determine the precipitate in a precipitation reaction, you should follow solubility rules. These rules provide guidance on the solubility of various compounds in water, helping you identify which compound will form a solid precipitate. By comparing the ions present in the reactants and applying solubility rules, you can determine the precipitate formed in the reaction.

What type of reaction produces the most dangerous radioactive waste?
What type of reaction produces the most dangerous radioactive waste?
What is the equation of iron and hydraulic acid?
The reaction between iron and hydrochloric acid can be represented by the following equation: Fe + 2HCl → FeCl2 + H2. This reaction produces iron(II) chloride (FeCl2) and hydrogen gas (H2).
What type of reaction involves oxygen and produces light and heat decomposition reaction double replacement reaction combustion reaction or combination reation?
The type of reaction that involves oxygen and produces light and heat is a combustion reaction.
